Pushengage MCP Server

@pushengage/mcp

Manage your PushEngage account from any AI assistant, in plain language.

PushEngage is a push notification platform for web push, mobile app push, WhatsApp, and on-site chat widgets, used to grow subscribers and recover revenue (cart abandonment, price drops, back-in-stock, and more).

This package is a Model Context Protocol (MCP) server. It connects MCP-capable assistants such as Claude Desktop, Claude Code, and Cursor to your PushEngage account so you can send and schedule notifications, run A/B tests, build audiences, inspect analytics, and manage site settings just by asking, without leaving your chat.

You log in once through your browser; the assistant then acts on your behalf against whichever PushEngage site you select.

What you can do

Once connected, just describe what you want. A few examples:

Send and schedule

• "Send a notification titled 'Sale ends tonight', message 'Last call, 50% off', linking to https://example.com/sale."
• "Schedule that for 9 AM in each subscriber's local timezone."
• "Set up a recurring digest every Monday and Thursday at 8 AM through the end of the month."
• "Run an A/B test of two headlines and auto-roll-out the winner by click rate."

Target the right people

• "Create a segment for visitors of /pricing."
• "Build an audience of gold-plan customers in the US and send only to them."

Understand performance

• "How many subscribers do I have, and what was my click rate over the last 30 days?"
• "List my active drip campaigns with their sent, seen, and clicked stats."

Configure a site

• "Set my default notification expiry to 7 days."
• "Change my site timezone to Asia/Kolkata and turn on geolocation."

Requirements

• A PushEngage account (free or paid) with at least one site.
• Node.js 18 or newer (the assistant runs the server via npx).
• An MCP-capable client (Claude Desktop, Claude Code, Cursor, or any other).

Install

Add the server to your client's MCP config. No global install is needed; npx fetches it on demand.

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or the equivalent on your platform:

{
  "mcpServers": {
    "pushengage": {
      "command": "npx",
      "args": ["-y", "@pushengage/mcp"]
    }
  }
}

Restart Claude Desktop. The "pushengage" server should appear in your tool list.

Cursor

Edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "pushengage": {
      "command": "npx",
      "args": ["-y", "@pushengage/mcp"]
    }
  }
}

Other MCP clients

Any client that speaks MCP over stdio works. Configure it to run the command npx -y @pushengage/mcp.

First run: logging in

Authentication is browser-based, so your credentials never touch the assistant.

1. Ask: "Log me into PushEngage." The server opens a browser tab to the PushEngage authorize page.
2. Click Authorize. The tab confirms success and an access token is saved locally.
3. Ask: "Show my PushEngage sites," then "Use site 12345" to pick the site to work with. The selection is remembered across restarts.

Every site-scoped tool acts on this current site unless you pass an explicit site_id. When the token expires you will see an AUTH_EXPIRED message; just ask to log in again.

Tools

All site-scoped tools default to the current site.

Configuration

No configuration is required — the server talks to PushEngage's production API out of the box. These environment variables are available for less common setups:

Running multiple PushEngage accounts side by side

Register the server under two different names, each with its own PE_MCP_CONFIG_PATH so the tokens don't collide:

{
  "mcpServers": {
    "pushengage-client-a": {
      "command": "npx",
      "args": ["-y", "@pushengage/mcp"],
      "env": {
        "PE_MCP_CONFIG_PATH": "/Users/you/.pushengage/mcp-client-a.json",
        "PE_MCP_CLIENT_NAME": "Claude Desktop (Client A)"
      }
    },
    "pushengage-client-b": {
      "command": "npx",
      "args": ["-y", "@pushengage/mcp"],
      "env": {
        "PE_MCP_CONFIG_PATH": "/Users/you/.pushengage/mcp-client-b.json",
        "PE_MCP_CLIENT_NAME": "Claude Desktop (Client B)"
      }
    }
  }
}

Ask the assistant to log in under each server name separately; each authorizes against whichever PushEngage account you choose in the browser.

Security and token storage

• Login is browser-based. The assistant never sees your PushEngage password.
• The dashboard sends the token to the server as a POST request, so it never appears in a URL, browser history, or access log.
• The token is stored at ~/.pushengage/mcp.json with 0600 permissions (readable only by you). Its expiry is set by PushEngage and is shown by pushengage_auth_status.
• To revoke it, run pushengage_auth_logout or log out of all sessions in PushEngage under Settings → Security.

Troubleshooting

The server won't connect at all ("Connection closed")

If npx -y @pushengage/mcp runs fine when you type it directly in a terminal, but your client (Claude Desktop, Cursor, etc.) shows the server as disconnected or logs something like MCP error -32000: Connection closed, this is almost always a PATH problem, not a bug in the server.

These clients are launched from your Dock/Finder, not from a terminal, so they never load your shell's startup files (.zshrc, .zprofile, etc). If Node was installed via a version manager (nvm, fnm, volta, ...), those tools only add node/npx to PATH from inside those startup files — so the client can't find npx at all, the server process never starts, and you get a generic connection error instead of a clear "command not found."

Fix: point the client at the absolute path to npx (this skips the PATH lookup for finding it) and also pass that same folder as PATH in env (so npx's own #!/usr/bin/env node shebang can find node when it re-execs). Run which npx in your terminal to get the path, then use it in your client's config:

{
  "mcpServers": {
    "pushengage": {
      "command": "/absolute/path/from/which-npx",
      "args": ["-y", "@pushengage/mcp"],
      "env": {
        "PATH": "/absolute/folder/containing/that/npx:/usr/bin:/bin:/usr/sbin:/sbin"
      }
    }
  }
}

Restart the client after editing. If which npx instead prints something under /usr/local/bin or /opt/homebrew/bin, your Node install isn't version-manager-based and this likely isn't your issue — check the client's own MCP logs for the actual error instead.

Other errors

• AUTH_EXPIRED — your token expired. Ask the assistant to log you in again.
• NO_SITE_SELECTED — call pushengage_list_sites and then ask to use one of the returned sites before using a site-scoped tool.
• Browser doesn't open — this happens in headless or remote (e.g. SSH) sessions. The authorize URL is printed to the terminal running the server; open it manually.
• Something else — every error the server returns starts with a [CODE] tag and a plain-language explanation; share that with support if you need help.
